A font with the little marks at the ends of the lines is a "serif" font. One such font is Times.

A font without the marks is a "sans serif" font. One such font is Helvetica.

A font is how text looks. A font group is a group of letters that have the same font.

In HTML:

<font size=1>Smallest</font>

<font size=3>Normal</font>

<font size=7>Largest</font>

The font tag can also have the color and face defined.

<font size=3 color=red face=arial>Normal</font>

However, the FONT tag is deprecated and has been removed from current versions of [X]HTML.

Instead, use CSS to specify font size. For example:

h1 {font-size: 2em; }

div.fineprint { font-size: .85em; }

The font size.
